The ER-20 Hi-Fi earplugs have a triple flange construction and provide an inexpensive, "high-fidelity" earplug that can be used in a variety of noisy environments.

Mainly used as an inexpensive Musician's Earplug, these plugs have principles to allow the user to still hear through a inserted resonator within the stem that allows outside tones such as vocal or musicial to be heard.

Low cost

Associated 20dB attenuation

Clarity of sound and pitch

Good frequency response accuracy

Speech is understood more easily in high level noise

Available in a variety of colors

The ER-20s are DIFFERENT than conventional earplugs. They actually reduce the dangerous sound level evenly (using a tuned resonator and acoustic resistor) to preserve the balance. You still hear the blend clearly, "feel" the bass, and are able to distinguish each tone.

Aircraft - crews, passengers, pilots

Athletics - athletes, coaches, spectators
